Believers! When you stand up for Prayer wash your faces and your hands up to the elbows, and wipe your heads, and wash your feet up to the ankles. And if you are in the state of ritual impurity, purify yourselves (by taking a bath). But if you are either ill, travelling, have satisfied a want of nature or have had contact with women and find no water then have recourse to clean earth and wipe your faces and your hands therewith. Allah does not want to lay any hardship upon you; rather He wants to purify you and complete His favours upon you so that you may give thanks.
